Patent GB-183293-A (GB)
Abstract: 183,293. Tyer & Co., Ltd., and Leake, F. W. May 11, 1921. Interlocking signals, points, and hand-levers.- On a single-track system the through road at a loop is provided with a warner signal arm 54 which is controlled by a slot lever 53 and by the winch 29 which operates the signals at the entrance to the loop according to the combination of points which are set and locked. The, points are locked when any signal is pulled off. Contacts 8, 9# 13, 14 at the points, and contacts 8<1>, 9<1>, 13<1>, 14<1> on the locking bolts complete circuits to indicators and to magnets 21, 22 in the station and, if the through line is set, to relays 5, 6 which complete contacts 17, 18 to indicators 19, 20 at the points and to the warner-signal slotlever lock-magnets 56. If both magnets 21, 22 are excited, the winch-locking magnet 28 may be energized by closure of the contact 33, and the winch 29 may be turned to right or left according to the direction of traffic and operates the selected signals. Operation of either the lever 53 or the winch 29 opens the circuit to the points-locking magnets 43, 44, 45, 49, 50, 51, thereby preventing movement of the points when any signal is off.

Abstract: 1,147,661. Copy holders. E. A. SIMPSON. 28 April, 1966 [29 April, 1965], No. 18575/66. Heading B6W. [Also in Divisions F2, G5 and H2] A reading training machine has a foldable rule or shutter 14 which is driven down a page by a spring and pulley drive mechanism 12 at a speed controlled by an eddy current brake assembly 16 (see Division H2). The case 10 is generally rectangular and is placed adjacent the book with rule 18 extending longitudinally across the page and the speed is set by adjusting slide 124 adjacent scale 152. The moving assembly is mounted on rod 32 which extends the full length of the machine. The rule 18 is attached to knob 64 which is spring mounted on to carrier 36, and is provided with detents (72, 74), Figs. 4 and 5 (not shown), so that it can be retained horizontal or vertical. The moving assembly is driven by constant force spring 78 wound on pulley 76 with its free end connected to carrier 36. The speed is controlled by eddy current brake 16 which is driven through gearing from wheel 90 which is, in turn, connected to carrier 36 by spring 94. Wheel 90 and associated gear wheel 82 forms a slipping coupling since the parts are held together by spring fastener 92 and thereby the rule may be pulled downwards over the page to by-pass illustrations and the like. Spring 94 is prestressed with the inner turns of greater radius than wheel 90 so that rule 18 may be raised on the page without turning the gearing.

Abstract: 644,131. Preventing lateral canting. LEYLANDS MOTORS, Ltd., and TATTERSALL, N. July 14, 1947, No. 18666. [Class 108(ii)] In a stabilizer for a road vehicle, a shaft set lengthwise of the vehicle either parallel, or at a small angle to its fore-and-aft centre line, has one end splined to a part which can rock about the axis of a vehicle axle or a parallel axis, and the other end splined to a part which can rock relatively to the chassis about a transverse axis, neither part permitting the shaft to rock freely about its own axis relatively to the axle and chassis respectively, so that tilting of the axle relatively to the chassis is resisted by torsion of the shaft and the shaft is stiff enough to restrain rolling of the vehicle chassis consequent upon such tilting. In the arrangement shown, a torsion shaft 13 is rigidly secured at its ends in aligned sockets 12, 12 of transversely disposed torque arms 11, 11, each of which is supported in aligned rubber bushes at the lower ends of pairs of depending links strapped to a back axle casing 2 and a vehicle chassis cross-member 3 respectively. The socket 12 of each torque arm 11 may be disposed centrally of the ends 10 of the arm or towards one end, as shown. If the proximity of the axle casing 2 and cross-member 3 does not allow of a sufficiently long shaft 13. the length of the latter may be effectively increased by employing a shaft having two telescopic parts, one end of each of which is secured to the respective torque arms, the other ends being welded or splined together.
